Command FPGA using Matlab

Do you have a QII subscription edition respective a license with allows you to use the SOPC/QSYS feature?

Do you have any HDL background?

In any case you've to implement logic into the FPGA that understands serial data received from the UART and

translates that into a high respective low on the aproppriate FPGA pin that is connected to you LED.

My MATLAB knowledge is very poor.

Is MATLAB able to transmit data (i.e. characters) over a console/UART?

Yes I can use SOPC an QSYS features with QII

Yes I have knowledges in VHDL, but not in verylog

But I don't know how to use SOPC. I have to place all component (UART and serail device)?

And yes with Matlab we can transmit data but i don't know how to do it but I'll find :)

That's good.

That's good either.

If you wish to extend your commanding by MATLAB in the future, is suggest that you implement

a NIOSIIe (the simplest) and a UART-Peripheral.

I recommend QSYS, because it (has already) superseded SOPC.

I'm not sure if ALTERA is provide a GPIO-Peripheral. This could be used to drive the LED-Pin.

You'll have to to create a QSYS-system with

NIOSIIe: Instruction Avalon Master -> On-Chip RAM that holds you code

NIOSIIe: Data Avalon Master -> GPIO-Peripheral Avalon Slave

NIOSIIe: Data Avalon Master -> UART-Peripheral Avalon Slave

After you've successfull described you system and build it, you'll have to instantiate it in a top-level (V)HDL Wrapper (or BSF) in QII.

After that worked you'll have to write your NIOSII-SW based on the Board-Support-Package QSYS created for you.

I guess that will be no simple task.

Do you need to control the board directly via MATLAB or is a command window sufficient? That would generate significant less

work in the FPGA, because you could exclude the NIOS and the SW part.

In that case you'll have to to create a QSYS-system with

JTAG-UART-Peripheral Avalon Master -> GPIO-Peripheral Avalon Slave

After you've successfull described you system and build it, you'll have to instantiate it in a top-level (V)HDL Wrapper (or BSF) in QII.

You could split your task in two phases:

1. Implemented the JTAG-UART based solution (gaining QSYS basic knowledge and establish a commanding interface to the PC)

2. Implement the NIOSIIe based solution (developing the sophisticated solution based on the knowledge gained in 1.)

Thanks,

I have implemented niosII on my fpga with the uart and serial device.

I have made a C program in order to send Hello World on serial port and it's successful.

#define RS232_UART_DATA ((volatile int*) 0x10001010)
# define RS232_UART_CONTROL ((volatile int*) (0x10001010+4))
int main()
{
    unsigned char hwld = {'H','e','l','l','o',' ','W','o','r','l','d','\0'};
    unsigned char *pOutput;
    pOutput = hwld;
    while(*pOutput) //strings in C are zero terminated
    {
         //if room in output buffer
         if((*RS232_UART_CONTROL)&0xffff0000  ) 
         {
            //then write the next character
            *RS232_UART_DATA = (*pOutput++); 
         }
     }
}

With this code my FPGA send "hello world" to my computer.

But now I would like to send information on my FPGA with serial port in order to control my FPGA.

I explain:

If I send '1' from my computer to the FPGA I would like that the LEDG(1) turn on.

If I send '2' the LEDG(2) turn on...

I don't know how to make it... I know that I have to take the information on RX but I don't know how to do it
